WINDING-BQX FOR AWNINGS.

SPECIFICATION forming part of Letters Patent No. 790,459, dated May 23, 1905. Application ined rebrary 23,1905. serial No. 247,013.

T0 @ZZ whom, it may concern.-

Be it known that I, JosnrH RICKERT, a citizen of the UnitedStates, residing at Chicago,

i-n the county of Cook and State of Illinois, have invented certain new and useful Improvements in Winding-Boxes for Awnings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relatesto improvements in winding-boxes for awnings.

The object of the invention is to provide a boX of this character which will be simple, strong, durable, light in construction, elicient in operation, andwell adapted to the lpurpose for which it is designed.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed. i

In the accompanying drawings, Figure 1 is a front lelevation of the improved windingboX. Fig. 2 is a side elevation thereof. Fig. 3 is a top plan view, and Fig. 1 is a central vertical longitudinal sectional view, of the same.

Referring more particularly to the drawings, 1 denotes a bracket-plate which is adapted to be liXedly mounted in any suitable manner and is here shown as being provided with 'screw-holes to receive screws or bolts for connecting the plate to the side of a building. On the base of the plate 1, adjacent to each edge of the same, are formed upwardly-projecting right-angularly-formed guide-flanges 2. On the plate 1, at the lower vend of the guide-flanges 2, is formed a laterally-projecting centrally-disposed supportingl plate or Slidably mounted on the plate 1, between the guide-anges 2,is a winding-'box 4, said box comprising an inner plate 5, on the opposite edges of which is formed an offset flange-en'- gaging portion 6. On the plate 5 and spaced from the same is an outer plate 7, said plate having formed on its upper and lower ends inwardly-projecting lugs 8, which are adapted to engage the outer face of the inner plate 5 and are rigidly connected thereto by means of .lixedly mounted a sprocket-wheel 12, around Vwhich is adapted to pass the sprocket-chain for operating the awning, said chain not being herein shown. On the upper lug 8 of the plate 7 is formed a pair of upwardly-projecting ears 13, between which is pivotally mount- A ed a right-angularly-formed gravity pawl or dog 14, the right-angularly-formed lower' endl of which is adapted to project inwardly and to work through a slot '15, formed in the outer plate 7, to engage the teeth of the sprocketwheel 12, ythereby holding said wheel against turning in either direction. The pawl or dog 14 is provided with an .offset or projection forming a linger-piece 16, whereby the same may be riveted todisengage the inner rightangularly-disposed end from the teeth of the sprocket-wheel.

Thelower lug 8 is provided on its upper side with a pair of upwardly-projecting ribs 17, between which is formed a bolt-hole 18, and in the plate or lug 3 is formed a bolt-hole 19. Said holes 18 and 19 are arranged in vertical alinement, and through the sameis inserted a retaining-bolt 20, the head of which is disposed between the ribs 17 on the lug 8, whereby said bolt is held against rotation to permit the nut 21 on the lower end of the same to be adjusted thereon. By adjusting the nut 21 on said bolt 20 the vertical upward movement of the winding-box or bracket plate will be limited. The sliding movement of the winding-boxV on the supporting-bracket is provided to permit said boX to accommodate itself to the various conditions of the winding-chain` so that slack'in said chain may be taken up and the .parts always kept in operative position.

In a winding, mechanism for awnings constructed as herein shown and described the usual pawl-and-ratchet connection is dispensed IOO with and in place of the same is arranged the gravity pawl or dog, which is adapted to directly engage the teeth of the sprocket-wheel to lock said Wheel against rotation in either direction, thus permitting the awning to be quickly adjusted and held in the desired position. By arranging the parts in this manner the strength of the winding mechanism is greatly increased and the construction of the same simplified. By constructing the winding-box in skeleton or open form, as herein shown and described, much less material is required and a much lighter construction is provided, the open form of box also preventing the accumulation of dirt and permitting the operation of the parts to be clearly observed.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention Will be readily understood Without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a device of the character described, the combination with a supporting-bracket having formed thereon parallel vertically-disposed guideways, an open box slidabl y mounted in said guideways and supported by said bracket, an adjusting connection between said box and said bracket whereby the upward movement of the former is limited, a winding-shaft journaled in said box, a sprocketwheel iixed on said shaft, and a pivoted, gravity-operated dog or pawl having an angular end extending into said box and adapted to engage the teeth ol said sprocket:- wheel, thereby locking the same against turning, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOSEPH RICKER'I.
